SANITARY CONTAINER.

Application filed December 6, 1926'. Serial No. 152,860.

This invention relates to improvements in containers for edibles of thatcharacter which are intended to be eaten directly from the container byapplying the mouth to one end of the container, and particularlyrepresents an improvement over the device shown in our co-pendingapplication for patent, filed December th, 1925, Serial No. 74,463. Inthis previous device, a sanitary 1 wrapper for that end of the containerintended to be applied to the-mouth was provided in the form of a skirtsurrounding the main body of the container at said end. This skirt wasformed integral with the blank from which the container was made and wasfolded down onto the blank before the latter was rolled. This not onlycalled for a folding operation apart from the rolling operation, butnecessitated tearing all the thicknesses of the container and skirtcompletely through when unsealingthe normally closed end of thecontainer, in order to then separate the skirt-from the body and allowthe skirt to fall off. The above fea- -tures made the containerrelatively expensive to manufacture and necessitated the use ofconsiderable strength to tear across the container when removing thesealing clip. This latter operation frequently caused the container tobecome distorted and warped before being put to its final and properuse.

The principal object of the present invention therefore is to eliminatethe above defective features by providing a sanitary removable wrapperfor the container so arranged that while formed integral with the blankfrom which the container is made, it eliminates the folding operationpreviously necessary, and does not require that the top 4 of thecontainer shall be torn across when removing the sealing clip.

A further object of the invention is to provide an im roved form ofsealing clip particularly a apted to this form of container and soconstructed that it may be readily removed when desired withoutmutilating the container.

A further object of the invention is to produce a sim 1e and inexpensivedevice and yet one WhlCh will be exceedingly effective for the purposefor which it is designed.

These objects we accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views:

Fig. 1 is a side elevation of our improved container, sealed.

. Fig. 2 is a view of the unrolled blank and extension from which thecontainer and the sanitary wrapping are made.

Fig. 3 is a perspective of the removable sealing clip.

Referring now more particularly to the characters of reference on thedrawings, the container is made from a. rectangular blank or sheet 1 ofsuitable prepared paper. The length of this sheet is equal to that ofthe finished container and itswidth is preferably about three times asgreat as the circumference of the finished container or so that thelatter will have three complete turns or wrappings of paper in itsmake-up.

Along one side edge the sheet is formed with an integral extension 2approximately half the heightof the sheet. Weakening means such as a rowof perforations 3 is placed along the vertical line of junction betweenthe sheet and the extension. The upper edge of the extension is alinedwith and parallel to the upper edge of the sheet. The initial portion Aof the lower edge. of

the extension, from the sheet 1 outwardly,

is also parallel to said upper edge for a distance approximating one anda uarter wrappings aboutthe container. Sal ed c then slopes upwardly atan acute angle 0 the-horizon as at B to join the outer side edge of theextension, which is very short. The total width or extent of theextension is sufiicient to wrap about the container two or more times. Asuitable adhesive 4 1s placed on the inner surface of the sheet 1'adjacent that side edge from WhlCh the extension projects and to theside of the row of perforations away from said extens1on.

The sheet is rolled on a mandrel in a suitable manner so that theextension Wlll be outermost. As soon as the main sheet is rolled theadhesive is moistened or applied so that the outermost vertical edge ofthe sheet will adhere to the wrapping thereunder. The extension is thenwrapped around the container. The wrapping operation be ing completedthe ends of the container are flattened or pinched together as at 5, andsealing clips are then applied to such ends. The lower sealing clip is aU-shaped member 6 of non-springy or bendable metal, which straddles thelower end Wrappings andis suitably pressed into place and thenpreferably indented to engage the paper as indicated at 7. This clip isnever intended to be removed, and is applied last. The upper clip 8 isalso U-shaped to straddle the upper end wrappings (which include theouter end portion of the extension 2) and when, applied to the containeris indented as at 9 to grip the paper. This clip however also hascentral tabs 10 depending therefrom on both sides and normally lyingadjacent the container. The clip 8 is applied first, while the containeris still on the mandrel, so as to prevent the extension 2 fromunwrapping. The contents of the container are placed therein from thelower end, which is then sealed by the clip 6.

When it is desired to open the container.

to consume or remove the contents, one or the other of the tabs 10 ispulled up and outwardly. This operation spreads the clip,

causing it to be disengaged from the paper and allowin it to be removedto expose the contents. T e extension member 2 not being secured to themain container wrappings along the top or down its side edge tends tounfold when thus freed from the clip, so that it may be then readilyunwrapped for its full extent and torn olf along the line ofperforations 3. The main container then remains unharmed and intact andits outer and upper portion will be in a perfectly sanitary condition,since up to this time such portion has been covered and enclosed by theextension. The lower edge of the extension being cut straight for theinitial portion of its extent, it insures that all the perforations willbe normally covered so that there is no chance for accidental tearingalong such perforations before it is desired to remove the extension.The sloping edge of the re mainder of the extension forms a spiral whenwrapped about the container, as shown in Fig. 1, this arran ementeliminating any tendency of said e ge to bulge outwardly so that itcould be readily torn, as would be the case if said edge were parallelto the axis of the container.

From the foregoing description it will be readily seen that we haveproduced such a device as substantially fulfills the objects of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practicesuch deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims. 2

Having thus described our invention what we claim as new and useful anddesire to secure by Letters Patent is:

1. A container including a tubular body formed by a sheet of flexiblematerial wrapped about itself, and an extension projecting from theouter side edge of the sheet wrapped completely about the body, saidextension projecting downwardly from the top of the sheet to a. pointshort of the bottom thereof.

2. A container including a tubular body formed by a sheet of flexiblemate-rial wrapped about itself, an extension projecting from the outerside edge of the sheet wrapped completely about the body, said extensionprojecting downwardly from the top of the sheet to a point short of thebottom thereof and adhesive material on the inner face of the sheet fromtop to bottom adjacent the junction of the extension therewith.

3. A container including a tubular body formed by a sheet of flexiblematerial wrapped about itself, an extension projecting from the outerside edge of the sheet wrapped completely about the body, said extensionprojecting downwardly from the top of the sheet to a point short of thebottom thereof, means for causing the outermost portion of the sheet toadhere to the wrapping thereunder from top to bottom, and weakeningmeans between the sheet and extension outwardly of the adhesive means.

4.
